I can't charge via PC cable anymore. I'm using the Nokia supplied cable, and get the "Insufficient Power..." message. Never happened before on either of the two devices I had, but now I can never get a charge. This was why I never liked USB port only charging, preferring the dedicated power cable. I could really use that Nokia charger port now.

I tend to use my N900 as a portable drive for samples in the studio, and the constant access is a power drain that is never satisfied, and I'm constantly unplugging from the PC to connect to a charger.

Is no solution or cause known?
